Polyethylene gas pipes have ascended to the pinnacle of choice for gas distribution systems due to their unmatched advantages. Their lightweight construction, inherent resistance to corrosion, and availability in various convenient coil lengths ensure easy, seamless installation via heat fusion or mechanical fittings. Since their pioneering debut in the 1960s, PE pipes have set the gold standard in reliability and durability, earning their place as the industry's benchmark for excellence.
Shandong Donghong Pipe Industry Co., Ltd. is at the forefront of innovation, proudly offering specialized PE pipes for mining applications. Our pipes are crafted using the advanced PE100-RC material-an enhanced iteration of the renowned PE100.This superior material brings a host of significant enhancements, including high Minimum Required Strength (MRS), exceptional Slow *** Growth (SCG), outstanding resistance to Rapid *** Propagation (RCP), and impressive melt strength LS. Perfectly tailored for gas transfer applications, these pipes provide robust anti-corrosion properties, remarkable flexibility, and ensure minimal medium loss, making them an ideal choice for the industry.

Anti-corrosion
Polyethylene (PE) is a remarkably durable and inert material, providing exceptional resistance to a wide range of chemical media. Withstanding nearly all except a few oxidizing agents, it remains unscathed by soil and water, ensuring no corrosive effects.
Secure Connection
Our pipes are predominantly joined using heat fusion butt joints and electrofusion. This method seamlessly integrates pipe joints and materials, ensuring that the interface strength is superior to the pipe body itself.
High Flexibility
With an impressive pipe elongation at break of ≥ 500%, our pipes offer exceptional flexibility, adeptly managing uneven soil settlement and exhibiting superior seismic performance.
Excellent Impact Resistance
Engineered to perform in low-temperature environments (-20ºC to -40ºC), these pipes resist external impacts, making them impervious to cracking or other damage.
Exceptional Cracking Resistance
Our pipes excel in resisting rapid *** propagation (RCP) and slow *** growth (SCG). This capability significantly reduces the risk of cracking and *** spreading, even under low temperatures or when installation damage occurs.
Low Friction Coefficient
Featuring a smooth inner wall with non-adhesive properties, our pipes maintain optimal conveying capacity, minimizing pressure loss throughout the pipeline.
Product Description:
- Low density, lightweight, and easy to handle and install.
- Offers corrosion resistance against various chemical mediums.
- Smooth inner wall ensures strong circulation capacity.
- Long service life: up to 50 years.
- High toughness with excellent seismic resistance.
- Enhanced resistance to slow *** growth (SCG) and rapid *** propagation (RCP).
